The intravascular catheter has a guidewire-receiving inner lumen extending along the length thereof. A first guidewire port is provided in the catheter body at or near the proximal end of the catheter, a second guidewire port is provided in the catheter body at a location spaced distally from the first guidewire port and proximally from a diagnostic or therapeutic element, such as a dilatation balloon, on a distal portion of the catheter and a third guidewire port is provided in the distal end of the catheter. The guidewire ports are in communication with the guidewire-receiving inner lumen.
